So when a Twitter user recently accused the legendary guitarist of "race baiting" for a Tweet in which Morello recalled an uncomfortable exchange with a hotel employee in North Carolina, Morello responded with all the visceral eloquence you might expect from a bi-racial punk rocker who graduated from Harvard with honors and a political science degree.

In his original Tweet, Morello appeared to suggest that the hotel employee was paying special attention to him because he is a person of color in a presumably upscale hotel.

That doesn't fit the definition of race-baiting, but it still triggered @doublegeenius enough to accuse Morello of being white, therefore implying that Morello does not know what he is talking about.

But the bi-racial Morello is no stranger to these comments, noting via his response on Instagram that he "changed colors" between childhood and adulthood. In a lengthy caption accompanying a screenshot of the Tweet in question, the rocker noted how he was black enough growing up that he was treated differently by his white peers — and even occasionally harangued with the n-word. He recalled once being handcuffed by a police officer for just walking down the sidewalk.

Then there was the time the Ku Klux Klan hung a noose on his family's house.

"So, you see, I was BLACK," Morello wrote. "Then later on I played in a famous band. The band's music had many of the markers typically associated with "white" hard rock music, we appeared in magazines and on radio stations generally reserved for white artists, my speech and vocabulary in interviews are not stereotypically 'urban,' and lo and behold there is a segment of my audience that freaks the f--k out whenever I reference being black. To them, I must be white. I MUST."

He chalked up the contradictions to a 'cognitive dissonance' among a segment of his fan base.

"When confronted with facts that contradict beliefs, people will try to find a way to resolve the contradiction to reduce their discomfort (Tom you are not black! Stop talking about race as if you are!)," he added, before in a few words apologizing for "singling out this one jackass..."

"...[B]ut it's an illuminating example," he concluded. "One more example of the complex and messed up issue race remains in the US in 2019."

Recently, Morello has been urging his social media followers to support prison reform. In a series of posts over the weekend, the former Audioslave guitarist called attention to the disproportionate number of minority Americans who are incarcerated for low-level crimes.

In observance of Mother's Day, Morello partnered with the ACLU of Kentucky to draw attention to the social cost of mass incarceration of women in the Bluegrass State, which jails women more than twice as often as the national average.
